Waitaki Boys' High School is preparing senior pupils for careers related to the primary sector.
This year it is providing agribusiness as a subject for boys in years 12 and 13.
Teacher in charge of agriculture Elizabeth Prentice said the new NCEA subject was provided in response to demand from pupils and their families.
The school has offered practical agriculture for years. Agribusiness added academic elements of science, economics, and analytical thinking, preparing the pupils for a wide range of future careers, Miss Prentice said.
She wanted to extend the boys, who were ''very good at underselling themselves''.
